what fule to use

[farmawi]

hay my friends it's an old stupid question so forgive me 😀
what fule should i use for a k5.9 in the temp. between 25c-34c temp.
is the 20% fule good or the 25% is better or a 30% ????????????.......

fuel

any of those will work, tuning for each will be different in order to control engine temps.

20% is cheapest
30% more expensive

IF you just playing around I would run the 20%

The more important factor is to buy a quality fuel. Stay away from Trinity Monster Fuel, its crap.

Run O'Donnel or Byrons.

ya I'm running byrons now and tornado before so if i do have a race you prefare to use a 30% fule cuz in my contry thay are all the same price 20,25,30% all the same price so you think that i should use a 30% fule but the hpi k5.9 manual says than not to use mor than a 25% fule

its all preference when it comes to fuel.

Part preference part whats available where you are.
If you are just bashing around 20% should be fine for you. If you want more kick go for the 30%. You will probably have to change the glow plug though and you will definitely need to re-tune.
I use trinity monster brew and haven't had any problems with it at all. I was using Odonnels but I got tired of the excessive residue it left on everything.
